way this work is done is that a mattress,`

woven of smallwillow saplings, is placed over the exactposition where the current or' the river is to'be dellected, and then the screen poles are sharpened and shoved tl'irough `the mattress six inches or the like, allowing, the small or upper ends ot these poles to stick up high enough to come above the surface of the water, 'when the mattress sunk to the bottom ot' the river hy plaeing are. usually held in substantially vertical positions by walings or Wale-pieces. The walepieces are arranged in spaced pairs with the poles passingl between them, and the walepieees are fastened to the regular hxed piling'. rlfhe screen poles are set some ten inches apart and they are intended to retard the tlow of the water through them in such a manner as to create an eddy otwater hehind them, and in very silty water this .retardation and eddying` allows the silt"to torm on top ol the rock ballast ot the mattress and gradually build up a bar. The process above set out is an old one and has heen used tor the last forty years on both the Mississippi and Ohio Rivers. Numerous devices have been made and proposed at dil'erent times tor securing` the screen poles to the `mattress and allowing the poles to stand in upright positions before the mattress is sunk. Ordinarily ,the ends ot the screen vpoles hare heretofore been either bolted to or laced in with the mattress by tie wires, in such a way that atter the mattress is sunk and there a recession of the river bottom betere the mattress comes to its final position ot rest, the screen poles will not pull loose from the mattress.

@the object oi'l this invention is the provision oit means tor securing the screen poles in position with respect to the mattress7 in such Amanner that the mattress may adjust itself slightly after it has been sunk and without moving the poles after they are in linal position, yet the poles cannot be pulled The screen pol-es NEW enteritis?

outof the mattress. Two forms of devices tor the attainment of. the stated object are illustrated and described in this application, each has thesa'm'e 'function as theot-her" and either can be employed alone, or both may hare to be used atdiilerent times in the same piece of work. Asfshown and en'plaii'ied both forms of screen pole securing 'means given as the basis ot' this application extend transversely below the mattress witihrespect to the endsl ofthe screen poles to 'which such securingmeans are attached. i i

Throughout the drawings and descriptien the same number is used to refer to the same part. .Y

, Considering the drawings, the river bed 1 has driven linto it the regular vertical piles 2, usually connectedby upper Wale-pieces `8 and similar lower pieces a. These pieces may be arrangedin parallel pairs/as illus trated in Figure 2. t

i In substantially vertical positions between the Wale-pieces are the screen poles, in any' number and spaced from each other at any chosen distance. Below the lower pairs of Wale-pieces ll the ends of the poles pass through the mattress 6 and into the river bedl; i Rocks are placed on the mattress Jfor the purpose of weightingdown or sinking and holding the mattress in place upon the 'F river bed.` Any suitable arrangement of rock ballast may be employed for the purpose stated but as the matress is illustrated in the drawings inits floating position the rocks. are Vnot shown thereon. IThrough the lower ends of the screen poles below the matressthere passed the securing flexible rod, chain or cable 8, 8, 8".

In Figure litwill be noted that certain of the screen poles just below the lower walepieces 4 are connected with each other by means of batting bars 9, and that the sets ol' screen poles thus coupled are hung to the Wale-pieces 4 by wires 10. The battings and the wire connections are temporary astenings to hold the screen poles in proper attitude and'to assist in supporting the mat tress, preparatory to the operation of sinking the mattress. y While thebatting bars 9 andthe temporary wire connections 10 are shown only in Figure 1 it is to be under stood that these same temporary connections are intended to be used with the form of the invention shown in Figure 6.

Considering the drawings Figures G to 10, it will be noted that in Figure 6 the river bed 1 and the regular piling 2, together with the wals-pieces 3 and l in parallel pairs are the same as before, as is also the mattress G. In this form of the invention the screen poles 1l have at their lower ends the pivoted toggles 12 held by bolts 13. It will be understood that the toggles 12 can be arranged lengthwise against the screen pole as illustrated in Figure 8, and while in such position the pole bearing the toggle may be thrust through the mattress. After the end of the pole bearing the toggle has passed through the mattress, the toggle is turned crosswise of the end of the pole, which plainly cannot now be withdrawn through the mattress.

employed together or separately.

It is held to he within. the purview of this invention to provide the end of the screen pole with two toggle members 12 one on either side oit the end ot'the pole.

As previously stated herein the two forms of` the screen pole securing devices may be The operation and ellect ot' both is the same. After the ends of the screen poles 5 have been passed.through` the mattress G, the flexible rods, 8, chain 8 or cable 8 below `the mattress prevents the withdrawal oi' the rods while` allowing a limited vertical movement ot' either rods or mattress. The same eilect is produced atter the toggles 12 have been turned crosswise oit the ends oi' the poles below the mattress, and any `pole may rise slightly, assuming that a stone might be encountered in the river bed which would pre vent the end o'lithe pole from passing into the river bed as far as the others. `The remaining poles will not be disturbed, and it is believed to be equally apparent from the drawings and the foregoing explanation that the mattress may rise slightly at any party without displacing the poles at that part.

Having now described this invention, I claim y l, In a construction `of the character described, the combination with fixed ailes, el Wale-pieces spaced apart andsecurec to the piles, a mattress, screen poles supported vertically by the said Wale-pieces and passing through the said mattress, and means con nected with the ends ol' the said poles below the mattress whereby the said poles are secured against removal and the said mattress allowed a movement up and down on the poles.
